I am trying to pass in a URL as a parameter to a TTURLMap like this:
[map from@"tt://person/(initWithURL:)" toViewController:
[PersonViewController class]];
I then have a TTStyledTableItemCell with links that render like this:
<a href="tt://person/http://persons.url.com/blah">Person name</a>
but when I click on these links the link doesn't call the initWithURL:
method in the PersonViewConroller class. I've verified things are
wired up correctly by passing in a simple string. I believe this
isn't working because the parser thinks the URL is part of the
TTURLMap url mapping. Is there a way to escape the person's feed url
(its a rest service that i need to use to pull info in)?
many thanks in advance.
I think the only character that TTURLMap trips up on is the / character, so the following did the trick for me. Just call these as Mike suggests on the way in and out of your init function
+ (NSString *)encodeTtUrl:(NSString *)str {
NSMutableString *temp = [NSMutableString stringWithString:str];
[temp replaceOccurrencesOfString:@"/" withString:@"__" options:NSLiteralSearch range:NSMakeRange(0, [temp length])];
return [NSString stringWithString:temp];
}
+ (NSString *)decodeTtUrl:(NSString *)str {
NSMutableString *temp = [NSMutableString stringWithString:str];
[temp replaceOccurrencesOfString:@"__" withString:@"/" options:NSLiteralSearch range:NSMakeRange(0, [temp length])];
return [NSString stringWithString:temp];
}
This is a common problem. I haven't found an elegant solution; the best I've been able to find is to manually escape the URL on the way in (e.g. by Base64-encoding it), and then manually unescape it inside your initWithURL: function. (Actually, you'd probably want to have a function called initWithBase64EncodedURL: or something like that, for clarity.)
